SAFETY PRECAUTIONS
There is always a danger present when using electronic equipment.
Unexpected high voltages can be present at unusual locations in defective
equipment and signal distribution systems. Become familiar with the equipment
that you are working with and observe the following safety precautions.
• Every precaution has been taken in the design of your MRD 5800 to ensure that
it is as safe as possible. However, safe operation depends on you the operator.
• Always be sure your equipment is in good working order. Ensure that all points
of connection are secure to the chassis and that protective covers are in place
and secured with fasteners.
• Never work alone when working in hazardous conditions. Always have another
person close by in case of an accident.
• Always refer to the manual for safe operation. If you have a question about the
application or operation call Sencore for assistance.
• WARNING – To reduce the risk of fire or electrical shock never allow your
equipment to be exposed to water, rain or high moisture environments. If
exposed to a liquid, remove power safely (at the breaker) and send your
equipment to be serviced by a qualified technician.
• To reduce the risk of shock the MRD 5800 must be connected to a mains socket
outlet with a protective earthing connection.
• For the MRD 5800 the mains plug is the main disconnect and should remain
readily accessible and operable at all times.
The MRD 5800 is equipped with an internal system battery. The MRD 5800
must be sent to Sencore service for replacement of this battery.
• When installing the MRD 5800 utilizing the DC power supply, the power supply
MUST be used in conjunction with an over-current protective device rated at 50
V, 5 A, type: Slow-blo, as part of battery-supply circuit.
• To reduce the risk of shock and damage to equipment, it is recommended that
the chassis grounding screw located on the rear of the MRD 5800 – be
connected to the installation’s rack, the vehicle’s chassis, the battery’s negative
terminal, and/or earth ground.
